The Lanczos algorithm is one of the principal methods for the computation of a small part of the eigenspectrum of large, sparse, real symmetric matrices. A single-vector, explicitly restarted variant of the Lanczos method is proposed in this paper. The algorithm ยฎnds only one eigenpair at a time usi
